Cual es el coeficiente de variacion de los resultados de 30,60,90,45?
alexdok [17]

based on the given results, the coefficient of variation can be found to be 45.54.

<h3>what is the coefficient of variation?</h3>

first, find the mean:
= (30 + 60 + 90 + 45) / 4

= 56.25

find the standard deviation using a spreadsheet:

= 25.61737691

the coefficient of variation is therefore:

= standard deviation / mean x 100

= 25.61737691 / 56.25 x 100

= 45.54
